Symptoms

High blood glucose levels lead to the symptoms of diabetes. These symptoms are often present leading up to a diagnosis of diabetes before treatment has started. They may return again after diagnosis if blood glucose rises again.

 

Common symptoms for type 1 diabetes include:

  • Increased thirst
  • Extreme fatigue
  • Frequent urination
  • Tummy pain
  • Weight loss
  • Feeling generally unwell
  • Dehydration. 

 

Symptoms for type 2 diabetes are similar, though some people with the condition do not have any symptoms at all. For others, the first indication may be a complication of diabetes such as heart attack, vision problems, or a foot ulcer.

 

Common symptoms of type 2 diabetes include:

  • Increased thirst
  • Increased urination, particularly at night 
  • Feeling tired and lethargic
  • Constant hunger
  • Slow healing skin sores
  • Itching skin and skin infections
  • Blurred vision. 

 

Your GP can organise a blood test to determine whether you have diabetes or a pre-diabetes condition.
